Date: Tue, 24 Jan 2012 18:15:52 -0500 (EST) From: David Miller <davem@...emloft.net> To: roland@...nel.org CC: sean.hefty@...el.com, hal.rosenstock@...il.com, linux-rdma@...r.kernel.org, netdev@...r.kernel.org Subject: [PATCH 1/3] infiniband: Convert dst_fetch_ha() over to dst_neigh_lookup(). Now we must provide the IP destination address, and a reference has to be dropped when we're done with the entry. Signed-off-by: David S.
